hattanffcit of New York, county and State of New. 'ork, have invented an Improvepro ' quality, utilizes hitherto unsuitable materials, and possesses new and advalitagou's properties; 7

The mixture is then cooled somewhat and thinned with turpentine, and this thinned mixture is allowed to settle and-age,

out of contact with the air,;for from six months to two years.

In an endeavor to improve this varnish and to permit the use therein of materials which are cheaper than the gums now employedin considerable quantity, we have discovered that. we may employ an aryl esterof an inorganic acid, and, in particular; that wemayus'etriphenyl hos hate (C HQ PQ tricresyl phos hate( H Po trinaphthyl phosphate H, 0, tri-monochlorphenyl phosphat H,c1 ,1 o,, triphcnyl phosphite (C,,H,,' ,,l0 triphenyl b'orate (C,H,,),BO,, 'etc., etc. At the present time we consider triphenyl phosphate to be the most desirable of the aryl esters of the inorganic acids and for that reason we shall describe the advantages of our invention with reference to this particular ester.

In employing-triphenyl phosphate with oil varnish we may add the triphenyl phosphoto to t e varnish as it exists, we'may smoother an Application filed lamb $3, 1921. Serial 10.454380.

substitute the triphenyl phos hate for part v of the gum constituent of t 'e varnish, or we may, substitute 'for phosphate-and a gum ordinarily unsuited for use in varnish, such as kauri, manila,

etc. The addition of the triphenylphos phateto the varnishmay be made'at any part or all of the gums commonly used a mixture of triphenyl stage. of the process from before the running untalla fter the period of at ever, ,the tripheny'l phosp ate has added before or during the running of the varnish the (process of running is much andfor-this; reason it-is probably desirable considerably more regular,

to add the triphenyl phosphateat thistime.

' We find that new oftriphenyl'phosphate'in any manner results in 'a; m-uch harder film which :is attheisitmetimemore flexible, brighter, smoother; less inflammable, and less subjecbtd checlrin or the production of minute';cracks int efilm. By substitutin for part- 0f in use, triphenyl phosphate alone, we substitute a new-and cheaper substance. andthus' widen the field of available materials and simultaneously reduce the cost of the-product. By substitutin as; the gums now used, tn henyl phos to and" gums at pnes ent considered unsuitable for oil varnish.

such asdkaurior manila, we are able not i only to employ a much wider variet of gums, but are also able to use gums w ieh are considerably cheaper than those now em ployed,and accordingly the use of triphenyl phosphate not only increases the material available for' the manufacture of oil var nish but also appreciably decreases the cost of the varnish.

In our use of the word gums we include all gums suitable for the purpose specified. It will be noted that in the examples of the products of our invention given above, such roduots do not contain compounds of cellu ose, such as cellulose esters, for which reason these compounds may be designated as non-cellulose or non cellulose ester materials.

Bay the term a complete oil varnish, as

use in the specification and claims, we

mean avarnish which has hitherto been considered'as com late, that is, a varnish which contains all t e necessary ingredients to make a varnish. In this case the addition by us of triphenyl phosphate to such a complete oil varnish serves to improve the quality of the varnish and to give to the same certain desirable qualities, as set forth in the specification.

As we have reviously stated, we now believe tripheny phosphate to be the aryl ester of the inorganic acids best suited to our uses, and for that reason we have described our invention and the advantages thereof with reference to this particular ester, but we also believe that similar advantages will result from the use of other aryl esters of inorganic acids and especially of other phenylic esters, and accordingly the description herein of one specific embodiment of our invention is to be regarded as illustrative only and not as in any Way limiting our invention.

The present application is acontinuation in part of our previously filed copending application. Serial No. 292,762, filed April 25, 1919. for varnishes.

We claim:
